Description

A kind of fruit coloring composition, fruit coloring functional fertilizer and application

technical field

The invention belongs to the field of plant growth regulators, and in particular relates to a fruit coloring composition, a fruit coloring functional fertilizer and applications thereof.

Background technique

1-Aminocyclopropanecarboxylic acid, referred to as ACC, was discovered in 1979 to be the immediate precursor for endogenous ethylene synthesis in plants. Its biosynthetic process is: methionine - S-adenosylmethionine - ACC - ethylene. Methionine is first converted into S-adenosylmethionine, which is catalyzed by ACC synthase to generate ACC, and ACC is oxidized to ethylene under the catalysis of ACC oxidase. When ACC is applied to plants, it has the iconic "triple reaction" of ethylene. Exogenous supplementation of ACC is an effective way to increase the concentration of ethylene in plants, and can replace the function of ethephon, a widely used ethylene release agent. .

Sumitomo Japan has registered ACC for fruit thinning of apple trees and nuts and increasing flower reversion, and the dosage of active ingredients is 100-600mg/L. The Chinese invention patent application with the publication number CN114989024A discloses the application of 1-aminocyclopropane carboxylic acid to promote the ripening and coloring of Clenson grapes, to promote the ripening and yellowing of tobacco, to increase the ratio of male and female flowers of cucumber, to promote the rooting of zucchini seedlings, and to thin flowers and fruits. Experiments show that when the effective concentration range of ACC is 300-500ppm, it can promote the rapid ripening and color change of Kelunsheng grapes, but attention should be paid to yellow leaves, dry leaves, and defoliation when the concentration is 1000ppm.

Another key factor for exogenous application of 1-aminocyclopropanecarboxylic acid to stimulate endogenous ethylene synthesis is ACC oxidase, whose activity is extremely unstable and depends on the integrity of the membrane. At the same time, the application of ACC alone may have the same application risks as ethephon preparations: it is easy to cause negative phenomena such as plant defoliation, fruit cracking, fruit shedding, and variety decline.
